Title:
LASER EMITTER, OPTOELECTRONIC DEVICE, AND DEPTH CAMERA
Document Type and Number:
WIPO Patent Application WO/2019/134671
Kind Code:
A1
Abstract:
A laser emitter (10), an optoelectronic device (100), and a depth camera (1000). The laser emitter (10) comprises multiple light-emitting elements (12). The multiple light-emitting elements (12) are irregularly arranged. The multiple light-emitting elements (12) are divided into multiple groups. The light-emitting elements (12) in each group of are regularly arranged. When the laser emitter (10) is operating, at least one group of light-emitting elements (12) are driven to emit a light beam to form a pattern. The multiple groups of light-emitting elements (12) are driven to emit light beams at different times to form multiple patterns.
